External rotation stress imaging in syndesmotic injuries of the ankle - Comparison of lateral radiography and radiostereometry in a cadaveric model

We compared the value of 7.5 Nm external rotation stress in diagnosing tibiofibular syndesmotic injuries of the ankle on lateral radiographs with radiostereometric analysis (RSA) in 10 cadaveric legs. After sectioning 2 ligaments, RSA showed an increase in posterior translation and external rotation of the fibula. This increase in posterior translation was smaller than the posterior displacement o

Characterization of a computer board-to-board ultra-wideband channel

In this paper we present the results of an extensive ultra-wideband (UWB) measurement campaign performed inside the chassis of two desktop computers. The purpose of the campaign is to analyze the possibility of board-to-board communications, replacing cable connections. Measurements of the propagation channel are performed over a frequency range of 3.1 - 10.6 GHz using a vector network analyzer an

Från Jesusrörelse till Jesus själv : Gerd Theissens utveckling inom jesusforskningen

Artikeln beskriver olika stadier i Theissens uppmärksammade forskning om evangeliernas tillkomstprocess och den historiske Jesus, med särskild uppmärksamhet på hans sena huvudarbeten. Theissen är numera kritisk mot den formhistoriska skepsis som läser evangelierna som en spegel av den tidiga kyrkan i stället för av Jesus. Idag hävdar han plausibilitetskriteriet som det avgörande. Just det att Jesu

Predator-prey encounter rates in freshwater piscivores: effects of prey density and water transparency

One of the most fundamental components of predator-prey models is encounter rate, modelled as the product of prey density and search efficiency. Encounter rates have, however, rarely been measured in empirical studies. In this study, we used a video system approach to estimate how encounter rates between piscivorous fish that use a sit-and-wait foraging strategy and their prey depend on prey densi

Triggering in quantitative diffusion imaging with single-shot EPI

PURPOSE: The aim of this study was to evaluate any possible effects of brain motion, CSF pulsations and other possible sources of physiological motion in electrocardiographic (ECG) triggered and non-triggered single-shot echo-planar imaging (EPI) measurements of diffusion. MATERIAL AND METHODS: Three different triggering protocols were evaluated in 6 healthy volunteers: 1) ECG triggering with time

Peripubertal moderate exercise increases bone mass in boys but not in girls: a population-based intervention study

On the basis of cross-sectional studies in elite athletes and longitudinal studies, physical activity in growing children has been suggested to enhance bone mineral acquisition and prevent osteoporosis later in life. The level of exercise in most of these studies is not applicable in a population on a day-to-day basis. The aim of this study was to determine whether moderate increased exercise with

Profiling of internalizing tumor-associated antigens on breast and pancreatic cancer cells by reversed genomics

Human antibodies directed towards functionally associated tumor antigens have great potentials as adjuvant treatment in cancer therapy. Here we describe an efficient subtractive approach to select single chain Fv (scFv) antibodies, specifically binding to unknown rapidly internalizing tumor-associated antigens (TAA) on human breast and pancreatic carcinoma cell lines. After re-engineering the scFv

Framtidsuttrycken i svenskans temporala system

Popular Abstract in Swedish De svenska framtidsuttrycken (futuralt presens, futuralt skola och futuralt komma) är alla kontextuellt betingade användningar av uttryck som också har andra funktioner. Syftet med min avhandling är att beskriva vilka kontextvillkor som måste vara uppfyllda för att de tre uttrycken ska fungera som framtidsuttryck. I den modell över svenskans temporala system som presentThe main aim of this study is to specify the contextual conditions that apply to the use of the three central expressions for the future in Swedish: the present form and the auxiliaries skola and komma. A tense suffix indicates a temporal domain and states that a mediating element, here called FIX, is placed in the indicated domain. The present suffix points to a domain that overlaps temporally wi

Higher Education for Girls in North American College Fiction 1886-1912

Twenty years after Vassar College welcomed the first American female undergraduates in 1865, the experiences of women college students began to be fictionalized in so-called college stories. This thesis shows how higher education is presented in the novels, collections of short stories, and serialized stories for female readers published before the United States was involved in the First World Wa

Glaucoma detection by Stratus OCT

Purpose: To investigate the diagnostic accuracy of retinal nerve fiber layer thickness (RNFLT) summary report parameters from Stratus optical coherence tomography (OCT) in glaucoma patients. Patients and Methods: We obtained Stratus OCT measurements of peripapillary circle scans (average values) of the regular image resolution "FAST RNFLT" protocol, and of 1 circle scan of the high resolution "RNF

Carbon cycling in subarctic tundra; seasonal variation in ecosystem partitioning based on in situ 14C pulse-labelling

Carbon assimilation and allocation were studied in a tundra ecosystem in northern Scandinavia. Seasonal variation in the below-ground carbon allocation to dissolved organic carbon (DOC), coarse-, fine-, and hair roots was investigated using in situ C-14 pulse-labelling, adding 2-3 MBq (CO2)-C-14, dm(-2) to the above-ground vegetation. Combining the allocation data with regression models of the sea

Common variants in the ENPP1 gene are not reproducibly associated with diabetes or obesity

The common missense single nucleotide polymorphism (SNP) K121Q in the ectoenzyme nucleotide pyrophosphate phosphodiesterase (ENPP1) gene has recently been associated with type 2 diabetes in Italian, U.S., and South-Asian populations. A three-SNP haplotype, including K121Q, has also been associated with obesity and type 2 diabetes in French and Austrian populations. We set out to confirm these find

Interactions between Sulfide Minerals and Alkylxanthate Ions .1. A Vibrational Spectroscopic Study of the Interactions between Sphalerite and Synthetic Zinc(Ii) and Cadmium(Ii) Sulfides, and Ethylxanthate Ions in Aqueous and Acetone Solutions

The crystal structures of zinc(II) and cadmium(II) sulphides are not affected by the stoichiometry of metal and sulphide ions at the precipitation of the two compounds. The composition and structure of the ultimate surface layers, and thereby the chemical properties of the particles, are on the other hand sensitive to the stoichiometry at the preparation. Chemisorbed ethylxanthate complexes are fo

Wave propagators for transient wave in one-dimensional media

Wave propagators are introduced for transient wave propagation in a general one-dimensional medium. The definition of wave propagators is based upon a wave splitting technique. Several properties for the propagators are given and the relations between the method of propagators and the invariant imbedding method and the Green function approach are discussed.
